I
carved Lana
from a 70
pound pound
block of
polyphant
stone.
One
side of the
carving is
left untouched
to show the
varied colours
of the stone
in its natural
state.
Lana
measures about
12.5 inches
high. 12.5
inches
long
& 4
inches wide,
and weighs about 50.25
pounds.
Polyphant stone is a type of Elvan, a
name used in Cornwall and Devon for
native varieties of
quartz-porphyry. Most
of the Elvan quarries are
now disused.
Greenstone
is another name for this stone.
It is
basically
a greenish-grey
in
colour, but is
often
flecked with other
unpredictable
colours from many
minerals and
other
impurities found
in the
stone.
Polyphant was often used for
parts of buildings such as doorways so
they could be finely carved.
Around 400 prehistoric
stone axes, made from greenstone, have been
found all over Britain, which from
petrological analysis appear to come from west
Cornwall. Although the quarry has not
been identified, it has been suggested that
the Gear, a rock now submerged half a mile
from the shore at Penzance, may be the site.
The
name Polyphant means 'Frog Pool' in Cornish.
